MAKE SENSE OF THE NUMBERS

An older model year changes more than the price.

A price gap is not a depreciation rate

These prices compare different vehicles on the market. An older model year may offer a lower asking price, but mileage, equipment and the mix of listings also change.

Condition needs its own check

History, equipment and physical condition can change the value of an individual car. A model-year median cannot confirm any of them.

Mileage is part of the comparison

A 2016 Cadillac CT6 asks about 47% of the 2020's typical asking price ($16,391 vs $35,106). The “Share of baseline ask” column in the table above shows the same share for every model year in between.

How many Cadillac CT6 model years can I compare here?

This depreciation curve covers 5 model years, from 2016 to 2020, each priced from dealer listings in the October 26, 2026 snapshot.

Is this a forecast of my car's resale value?

No. These are dealer asking prices for different vehicles in a dated snapshot. They do not measure the value lost by one car over time, original MSRP depreciation, or final transaction prices.

How does mileage affect Cadillac CT6 asking prices?

Open a model year to see its available odometer groups, asking prices and listing counts. Mileage is the distance recorded on the odometer. Price differences also reflect condition, trim and equipment; sparse groups are labelled separately.

Where these numbers come from

Compiled by VinAssessment from dealer listing data. Prices shown are asking prices, not completed transactions.

Market & currency
United States · USD · all available trims
Data snapshot
October 26, 2026
Typical price
Median asking price per model year, or the average when the median is unavailable. The price basis is labelled on each row.
Price range
25th–75th percentile: the middle half of the listing sample, not a confidence interval. Missing ranges are not estimated.
Coverage
5 qualifying model years with at least 10 listings each. Headline price-gap calculations require at least 25 listings per year. Gaps in data do not establish a generation change.
Mileage groups
Only positive, usable odometer readings. Groups with fewer than 5 listings are observations, not dependable market estimates. Reported odometer readings do not verify actual lifetime mileage.
What is not measured
Original MSRP loss, future resale value, or a guaranteed price for an individual VIN.
